TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN W. ADAMS, of Spring Creek, in the-county of Adams, and in the State of Wis. cousin, have invented certain new and useful Improvements in 'Car-Coupling; and do hereby declare that the following is a full, clear, and exact description thereof, reference being hadjto theaccompanyingdrawings, and the letters of reference marked thereon. In the annexed drawings, making a part of this specification-.-

- Figure 1 represents a side elevation of my car-coupling, with the pin down or the link ooupled, and

Figure 2 represents the same with the pin up and the link uncoupled. j

In the annexed drawings, A represents the ordinary draw-head or bumper of a car, and

53 represents the ordinary link for coupling or attaching cars together. 1

0 represents the coupling-pin, the upper end of, which is made square, and so as to work in thecaso or frame K, which is secured to the top of the draw-head A, and is providcdwith projections, r iandz, on one side thereof. The projections 1' and z are for the purpose of catches or hooks to lock with the upper end of the spring-lever'h, and thereby hold the pin 0 up out of the way, when desired. I 1

D represents a spring secured to the topot the chamber in the draw-head, and providcd with a-r'od projecting upward from it, as seen at g, and with arms across the front end of it-y just so as to work up and down between the sides of the draw-head. i

A small chain or cord, 2:, attached to the pin Q and rod g, connects sa id pin and spring D together. The. spring D operates and serves the double purpose of forcing the pin 0 down, when desired, and when the projections r or care detached from the top of the lever h, and to hold the link 13 in a horizontal position, so as to guide it towards and into the mouth'of another draw-head. it

The leverlt is secured or pivoted, as shown, to the side of the case or fram'eK, andhas a rod, j, cxtondin'g from its lower end out horizontally through jhe'front. end of the draw-head. A small spring,f, is adjusted behind the lever h to keep the same firmly in place. i

To use this device the operator raises or draws up the'pin C, by means of a snitable ring or loop in the top thereof, and the'rebydraws the spring D up out of the way, until th'c projcction z catches over the upper end of the lever It, as shown in fig. 2 of the drawings, when the link B, and therefore the cars, are unccupled. The pin 0 is left in the position above described, until it may be required to couplegithe car with another, which is run up toward and against it, so that the bumper or draw-head A strikes againstithc rod j, which detaches the lever'lt, and the pin 0 is forced quickly down through thc'link B. i I i I represents a hook which is pivoted in the opposite draw-head. Thisfhook has a rou'nded fron t,-in the rear; r of which a piece is out out, as shown, so as to form a front and rear shoulder. This hook lieson a spring so as to keep it close against the top of the draw-head, and keep the link stationary when secured therein.

What I claim, is i The arrangement of the lover h and rod with the pin G and spring D,- when constructed as described, and operated by the link D, secured substantially as set forth and for the purposes specified.

In testimony that I claim the foregoing, have hereunto set my hand, this'ioth day of February, 1868. i l
